Medication and Heat

Written on 04/22/2026

Prescription and over-the-counter medications can negatively impact our ability to safely work in heated environments. Certain medications can:

  • Reduce the thirst sensation
  • Interfere with the ability to control the body’s temperature
  • Impair the ability to sweat and properly cool the body
  • Increase the risk of fainting and falls
  • Cause electrolyte imbalances
  • Create skin sensitivity to the sun

UCOR Health Services performs comprehensive occupational medical evaluations to provide initial and continuing health assessments. A medical history that includes information such as the worker’s current health status; past medical, occupational, immunization, and smoking history; lifestyle factors; allergies; and prescribed and nonprescription medications should be provided via Form-1608, Medical Questionnaire.

Examples of medications that may increase heat-related risks include:

  • Diuretics
  • Beta blockers
  • Calcium channel blockers
  • ACE inhibitor and ARB blockers
  • Psychiatric medications
  • Antiseizure medications
  • Stimulants used to treat ADHD
  • Antifungals
  • Antibiotics such as tetracyclines and fluoroquinolones can increase sun sensitivity
